Look into replacing Enzyme with ReactTestUtils

[sarahscott]

Enzyme doesn't support the new version of React, and it could become difficult to maintain in the future. We should try to use the ReactTestUtils instead.

Can you add the link to the Enzyme ticket?

[sarahscott]

enzymejs/enzyme#953

[alloy]

Done in #583

[orta]

[moved to #559]

[orta]

also ReactTestUtils only are for react-dom I think

[alloy]

Not this ticket, I think, because this ticket was about removing enzyme.

And what’s the problem with ReactTestUtils being liited to react-dom?

[orta]

React-dom is only for the web

[orta]

Alright, I'll bring #559 back to life

[alloy]

Hrm, afaik ReactTestUtils is supposed to work fine with RN.

[orta]

They require a DOM, which RN doesn't have, for example:

import * as React from "react"
import * as ReactTestUtils from "react-dom/test-utils"

  it("calls goto Artist on to the artist button", () => {
    const testFunc = jest.fn()
    const d = ReactTestUtils.renderIntoDocument(<TODO goToArtist={testFunc} />)
    const a = ReactTestUtils.findAllInRenderedTree(d, c => true)
    console.log(a)
  })

Doesn't load:

Ah right, you’ll probably need to add JSDOM or something
